Installation Location
• Avoid placing the PS-A next to other devices that might cause overheating.
• Keep the PS-A away from arc-generating devices such as magnetic switches and non-fuse breakers.
• Avoid using the PS-A in environments where corrosive gases are present.
• To ensure the reliability, operability and ventilation of the PS-A, be sure to install it in locations that are
more than 50mm away from adjacent structures or equipment. Also, consider the need for installing or
removing expansion boards, or connectors when designing and installing your PS-A.
Vibration and Shocks
If the PS-A is moved when its enclosure doors are open, or while it is installed in a rack equipped with caster
wheels, or when using a stand with an arm attached or when attached to a wall, the hard disk can receive
excessive vibration or jolting. Be especially careful at this time.
• Be sure not to move the PS-A unit while the HDD is starting up. This can lead to a
machine breakdown (Even a slight movement of the PS-A should not be per-
formed).
• When using a fan to cool the PS-A unit, be sure that the fan does not point
directly at any of the PS-A’s disk drive units.
